Nature and Objects of the Invention.

My invention relates to machinery for reducing metal between dies, oneof which reciprocates and is driven by a toothed or cam-wheel; and itconsists in certain novel combinations and arrangements of parts, whichhave for their object to make a simple, effectual, and rapid machine forthis purpose, as will be fully set forth.

Description of the Drawing.

Figure 1 is a top view of my improved machine. Fig. 2 is a sideelevation of the same. Fig. 3 is a longitudinal vertical section throughthe center of the machine. Fig. 4 is a similar section through thespindle H and the bracket that supports it. Fig. 5 is aview of thepulley F which drives the spindle H. Figs. 6 and 7 are enlarged views ofthe dies used in drawing wire to a circular form. Figs. 8 and 9represent the shape of the dies used when a square form is given to thewire.

General Description.

A represents the bed of the machine. It is provided with suitablebearings for the shaft B, and has secured to it the pieces J J, in whichthe reciprocating stock L M slides. The shaft B carries the cam-wheel O,and has a band or fly-wheel, E, secured upon one end, and a pulley, 1),upon the other. A bracket, G, secured upon the side of the frame,supports the spin dle H and the pulley F. Motion is given to this pulleyto drive the spindle through the medium of the belt S. The spindleslides in the mandrel c, to which the pulley F is secured, and it isprovided with a feather, d, which fits in a groove in the mandrel 0, sothat, as the pulley revolves, the spindle will turn with it. The lengthof the feather permits it to be with drawn at pleasure from the mandrel0, so that the spindle may be disconnected from the pulley and thelatter permitted to revolve without imparting its motion to the spindle.R represents a chuck for holding the lengths of wire to be acted upon bythe dies. It is secured upon the end of the spindle H and turns with it.P represents the block which holds the stationary die a. It is securedin place by the screw j, and may be removed when it is desired to changethe dies. The reciprocating stock, which carries the die I), is composedof the two blocks L M, connected and operated by the right-and-left-handscrew 0, which works in properly-threaded chambers in the ends of theparts L M. The forward motion of the die I) is given by the cam 0against the roller Q, and the return motion is produced by the spring isplaced in the space beneath the dies and bearing against the block L, asshown in Fig. 3. The screw-stud O, by which the length of thereciprocating stock is regulated, is operated by the nut N fixed on thestud and projecting through a slot in the plate K. When the nut N isturned the blocks L M are either moved toward or away from each other,according to the direction in which the stud O is moved, so that thelength of the stock L M is thereby reg- .ulated, and made either longeror shorter, as

desired. This arrangement enables the distance between the stationaryand reciprocating die to be accurately adjusted, and causes them to workwith the best effect upon the wire. K is provided with a small stud orpost, 9, projecting from its upper surface, which forms a stop againstwhich the set-screw f strikes at each backward movement of thereciprocating stock. The set-screwf works in a small post, e, whichprojects from the block M through a longitudinal slot in the plate K, sothat the extent of throw of the stock carrying the die b is regulatedbyturning the screw f. This arrangement is plainly shown in Fig. 3.

When other than a round form is given to the metal it becomes necessaryto disconnect the pulley F from the driving-pulley, so that no rotarymotion shall be given to the spindle H.

The dies a b are held in the blocks by the screws ha, and may be removedto permit others to be inserted.

By the use of dies of proper form, and the manner of holding the metalto be acted upon, any desired shape may be given to it.

The plate.

I am aware that dies and swages of different shapes and sizes forreducing metal are in general use and well known; and I am also awarethat patents have been granted to several per- 2. The combination, withthe dies a b and stock L M, made adjustable by the screw 0, of the screwf, posts 0 g, and spring k, for regulating the motion of the stock L Msubstantially as described and specified.
